Description

A kind of expansion of caravan level prevents the system of clamping

Technical field

The utility model relates to caravan equipment technical field, prevents from clamping more particularly to a kind of expansion of caravan level and be System.

Background technique

In recent years, caravan was quickly grown, and caravan has concentrated lodging, food and drink, transport, amusement to be integrated, in terms of tourism, room Vehicle total sales volume is being stepped up, and helps people to walk close to naturally, getting close to naturally, caravan has concentrated house and car dual function, But because of the limitation of caravan volume, overall space is relatively narrow in caravan room, in household electrical appliance, under daily necessity is placed, room Interior space more seems crowded, for this purpose, caravan has carried out spatial spread mostly, is mainly for caravan to sideways expansion and rearward Car door extension, increases the interior space under dead ship condition, expands, uses by long-time, such as outward due to expanding cabinet Fruit uses in field, stuck phenomenon occurs, and expanding body recycling does not return, caravan ' casting anchor ' occurs, be easy to cause security risk, For this purpose, the utility model, which provides a kind of expansion of caravan level, prevents the system of clamping, when field uses, can be realized pair The protection of caravan carriage body avoids accident of casting anchor so that caravan carriage body is withdrawn.

Utility model content

The utility model prevents the system of clamping, Neng Gouyou mainly solving the technical problems that providing a kind of expansion of caravan level Effect realizes the protection in caravan expanding course, avoids that contingency occurs.

A kind of caravan level expansion prevents the system of clamping, including four movable stands, wherein four movable stands are divided into Bilateral symmetry is provided with two power racks on movable stand, is respectively provided with motor A and motor on each power rack B, motor A and motor B are connected to isochronous controller by data line, are provided with branch hold mode in four movable stand lower end connections Block, supporting module uses upward power, in the case where expanding body blocks state, realizes to the upward power of movable stand and thrust, then realizes The withdrawal of expanding body avoids stuck.

The supporting module, including pedestal, are provided with piston/cylinder on pedestal, and piston/cylinder uses cylindrical structure Form, piston/cylinder are divided into two component parts of cylinder barrel and cylinder tube, are provided with drive end bearing bracket and rear end at piston/cylinder both ends Lid, drive end bearing bracket and rear end cap are made of steel alloy metal material.

It is provided with piston core in piston/cylinder, piston rod is connected on piston core, is provided in one end of piston rod It has a haircut, push top moves up and down under the active force of piston rod in work, completes thrust process.

Wherein, connection is provided with two air pressure imports on cylinder barrel, and two air pressure imports have been separately connected pulsometer, leads to It crosses pulsometer and provides power resources for the piston rod movement of pneumatic cylinder.

Piston rod during the motion, is provided with two circular sealings between piston rod and pneumatic cylinder in order to prevent Circle, a kind of optimal technical scheme, the lid sealing ring are made of polytetrafluoroethylene material.

Cylinder tube is arranged in cylinder barrel lower end, and upper and lower two pouring orifices are provided on cylinder tube, are connected to by pipeline Oil syringe realizes that the piston rod of cylinder tube moves up and down by the pressure of oil syringe.

For buffering cavity work, two horizontal spring structures are provided in cylinder barrel, in the drive of spring structure The lower reset for completing piston rod, is provided with spring, can be improved the service life of pneumatic cylinder.

Movable stand is connected in push top upper end, under movable stand blocking case, is realized and is resetted by the thrust of supporting module.

The utility model has the beneficial effects that：A kind of caravan level expansion of the utility model prevents the system of clamping, whole to tie Structure is compact, can effectively realize the protection that carriage body is expanded to caravan, and avoid the destruction to barrier, economic and practical, Neng Gou great The big service life for improving expanding body being capable of application solutions expansion part in the case that in field, caravan expands failure Withdrawal.
